Standard System Connections
Required field connections to place the 8300G into
operation are as follows:
1. *Connect the solar panel cable to the system power
supply, SPS-12, figure 6.
Note: the solar panel should be mounted free of
obstructing shade and should be facing south in the
northern hemisphere or facing North in the southern
hemisphere.
1a. *If your system was ordered with the optional
LPS120/240 power supply, AC power should be
connected in accordance with explosion-proof code
via a termination junction box (not shown) to be
attached to the conduit provided at the upper left
side on the system enclosure. The power require-
ment for 120VAC will be 100 mA. The power
requirement for 240VAC will be 50 mA. These
power inputs must be fused with a maximum of
15A,
figure 7.
2. Connect the flow signal device to the termination
block located in the system control enclosure, figure
8, refer to the Wiring Control Document on page 116
in Appendix D .
2a. If used, connect the optional Inhibit Input signal to
the termination block located in the system control
enclosure,
figure 8, refer to the Wiring Control
Document on page 116 in Appendix D .
2b. If used, connect the RS-485 communication wiring
as required to the termination block located in the
system control enclosure,
figure 8, refer to the
Wiring Control Document on page 116 in Appendix D .
